中文拼音 [qīngwàilěng]
氫外冷
英文
hydrogen outer cooling-
The hurricane blast of stellar winds and blistering ultraviolet radiation within the cavity is now compressing the surrounding walls of cold hydrogen
空穴中星風的擊波和熾熱的紫外線輻射正在壓縮周圍冷氫氣形成的墻。The hurricane blast of stellar winds and blistering ultravioletradiation within the cavity is now compressing the surrounding walls ofcold hydrogen. this is triggering a second stage of new star formation
空穴中星風的擊波和熾熱的紫外線輻射正在壓縮周圍冷氫氣形成的墻。由此觸發了第二階段新恆星的形成。The theoretical analysis of large cryocondensation pump for nbi was mainly concerned. this paper emphasized on analyzing and calculating the heat load of cryocondensation pump, simulating thermal transmission coefficient and molecule transmission coefficient of radiation baffle according to monte carlo method, analyzing the process on cryo - surface and the factor of affecting pumping speed and hydrogen layer thickness of influencing cryo - parameter, etc. finally by verifying the pumping speed on large cryocondensation pump for neutral beam injection system, the pumping speed of 4. 0x105l / s ( for h2 ) was proven to be reasonable
本文首先介紹了中性束注入系統的國內外發展狀況，闡述了中科院等離子體所ht - 7中性束注入系統的構成，主要對用於中性束注入系統的大型低溫冷凝泵的特性進行了理論分析；對冷凝抽氣面的熱負載進行了分析計算；用蒙特卡羅法對輻射擋板的分子傳輸幾率與熱傳輸幾率進行了模擬計算；研究了低溫表面的處理方法對抽速的影響以及氫層厚度對各低溫參數的影響；最後對用於中性束注入系統的大型低溫冷凝泵的抽速進行了驗證，得出的結論是：選取40萬升秒的抽速是合理的。
